"99.91%" survival rate means "1 in a thousand chance of dying". Those aren't odds people ordinarily enjoy taking. Applied to the entire United States, it would still be 300,000 dead -- about the number of American dead in World War II.

Those 9s look great until you realize we're talking about dying. (And that's before we take into account the possibility of long-term disability.) "Low odds" times "Maximally bad outcome" means "take significant efforts to avoid".

Like maybe minor lifestyle changes, such as not going out to restaurants. Even if that's bad for restaurant owners because, ya know, death.
